Ligamentum sacrococcygeum laterale

Ligamentum sacrococcygeum laterale

The Ligamentum sacrococcygeum laterale is a ligament located in the pelvic region of the human body. It connects the sacrum, which is the triangular bone at the base of the spine, to the coccyx, commonly known as the tailbone. This ligament plays an important role in providing stability and support to the sacrococcygeal joint.

Anatomy

The Ligamentum sacrococcygeum laterale is a strong fibrous band that extends from the lateral aspect of the sacrum to the lateral aspect of the coccyx. It is situated on either side of the midline, forming a bilateral structure. The ligament is composed of dense connective tissue, primarily collagen fibers, which give it its strength and flexibility.

Function

The main function of the Ligamentum sacrococcygeum laterale is to stabilize the sacrococcygeal joint. This joint is formed by the articulation between the sacrum and the coccyx. The ligament helps to maintain the alignment and position of the coccyx, preventing excessive movement or displacement.

Additionally, the Ligamentum sacrococcygeum laterale also contributes to the overall stability of the pelvic region. It assists in supporting the weight of the upper body and transmitting forces from the spine to the pelvis during activities such as walking, running, and sitting.

Clinical Significance

Injuries or abnormalities affecting the Ligamentum sacrococcygeum laterale can lead to pain and dysfunction in the sacrococcygeal region. Common conditions associated with this ligament include sprains, strains, and tears. These injuries can occur due to trauma, repetitive stress, or degenerative changes.

Treatment for ligamentous injuries typically involves conservative measures such as rest, physical therapy, and pain management. In severe cases, surgical intervention may be necessary to repair or reconstruct the damaged ligament.
